Maintenance and upkeep of the bending machine

Daily maintenance and upkeep

1. Cleaning work

After work every day, the workbench, mold, and surface of the bending machine should be promptly cleaned of dust, oil stains, metal shavings, and other debris to keep the equipment clean. Clean cloths and specialized cleaning agents can be used for wiping. Clean the dust inside the electrical control cabinet to prevent dust accumulation from affecting the heat dissipation and normal operation of electrical components. For example, conducting comprehensive cleaning work at least twice a week based on actual usage can effectively extend the service life of the equipment.

2. Check the lubrication system

Check if the lubrication system of the bending machine is working properly and ensure that all lubrication points are fully lubricated. Regularly add or replace lubricating oil, and choose the appropriate brand and model of lubricating oil according to the requirements of the equipment manual. Pay attention to checking whether the oil circuit is unobstructed to prevent blockage. Generally speaking, the lubrication condition should be checked every 50 hours of work, and if insufficient lubrication is found, lubricating oil should be added in a timely manner.

3. Check the fasteners

Regularly check whether the fasteners of the bending machine are loose, especially the connecting bolts, nuts, etc. If there is any looseness, it should be tightened in a timely manner. Check whether the installation of the mold is firm to prevent the mold from loosening or falling off during operation. For example, conduct a comprehensive inspection of fasteners once a month to ensure the stability of the equipment.

4. Check the electrical system

Check whether the wiring of the electrical system is secure, and whether there are any damages, short circuits, or other phenomena. Check the working status of electrical components, such as contactors, relays, switches, etc., to ensure they are functioning properly. If there is any abnormality, it should be replaced in a timely manner. Regularly conduct insulation tests on electrical systems to ensure the safety of equipment. Usually, an electrical system inspection is conducted every two weeks to promptly identify and resolve potential issues.

（2） Regular maintenance and upkeep

1. Accuracy adjustment

Regularly inspect and adjust the accuracy of the bending machine, including angle accuracy, straightness, etc. Professional measuring tools such as angle rulers, level gauges, etc. can be used for testing. If there is any deviation, it should be adjusted according to the equipment manual. Generally, precision adjustment is carried out quarterly to ensure the machining accuracy of the bending machine.

2. Maintenance of hydraulic system

Regularly check whether the pressure of the hydraulic system is normal, and adjust it promptly if there are any abnormalities. Check the quality and level of hydraulic oil. If the hydraulic oil deteriorates or the level is too low, it should be replaced or added in a timely manner. Clean the filter of the hydraulic system to prevent impurities from entering the hydraulic system and affecting the normal operation of the equipment. For example, the hydraulic oil should be replaced and the filter should be cleaned every 2000 hours of operation.

3. Maintenance of mechanical components

Regularly inspect the mechanical components of the bending machine, such as the slider, guide rail, screw, etc., for wear and tear. If there is wear and tear, it should be replaced or repaired in a timely manner. Lubricate mechanical components to reduce wear and extend their service life. Check whether the belts, chains, etc. of the transmission system are loose, and adjust them in a timely manner if they are loose. Generally, a comprehensive inspection and maintenance of mechanical components is conducted every six months.

4. Safety device inspection

Regularly check the safety devices of the bending machine, such as emergency stop buttons, safety barriers, protective barriers, etc., to ensure that they are working properly. Ensure the sensitivity and reliability of safety devices to ensure the safety of operators. Conduct a monthly inspection of safety devices to ensure they can function properly in emergency situations.

（3） Maintenance precautions

Maintenance work should be carried out by professionals to ensure correct and safe operation. Before maintenance, the power supply of the bending machine should be turned off and warning signs such as "Do not close" should be hung. When replacing components, choose components with the same specifications and models as the original equipment to ensure compatibility and stability of the equipment. During the maintenance process, attention should be paid to protecting the surface of the equipment to prevent damage such as scratches and collisions. Regularly record maintenance work to facilitate tracking of equipment maintenance status and timely detection of problems. For example, after each maintenance, detailed records should be kept of the maintenance content, replaced parts, discovered problems, and other information to provide reference for subsequent maintenance. In short, the maintenance and upkeep of the bending machine is a long-term and important task. Only by doing a good job of maintenance and upkeep can we ensure the stable performance and reliable accuracy of the bending machine, improve production efficiency, and extend the service life of the equipment.
